God is Already at work0

You come to know God by experience as you obey Him and He accomplishes His work through you.+

15 The Lord said to Moses, “Why are you crying out to Me? Tell the Israelites to break camp. (Exodus 4:15)
Then Moses stretched out his hand over the sea, and all that night the Lord drove the sea back with a strong east wind and turned it into dry land. The waters were divided, and the Israelites went through the sea on dry ground, with a wall of water on their right and on their left.  The Egyptians pursued them, and all Pharaoh's horses and chariots and horsemen followed them into the sea. (Exodus 4:21-23)
 26 Then the Lord said to Moses, “Stretch out your hand over the sea so that the waters may come back on the Egyptians, on their chariots and horsemen.” 27 So Moses stretched out his hand over the sea, and at daybreak the sea returned to its normal depth. While the Egyptians were trying to escape from it, the Lord threw them into the sea. (Exodus 4:26-27)
